3-rearrangement is observed when treating 2-methoxyquinolino-3-lithium with an α -C substituted deoxybenzoin, and this rearrangement yielded an unusual 3,4-disubstituted 3,4-dihydroquinoline. Several similar reactions were designed and executed to investigate this novel 1,3-rearrangement, and a mechanism involving a nucleophilic addition and a following 1,3-rearrangement with an unusual dearomatization
摘要当用α-C取代的脱氧安息香处理2-甲氧基喹啉-3-锂时,观察到一个新的亲核的1,3-重排,这种重排产生了一个不寻常的3,4-二取代的3,4-二氢喹啉。设计和执行了几种类似的反应来研究这种新颖的1,3-重排,并提出了一种涉及亲核加成反应和随后的1,3-重排以及喹啉环上不寻常的脱芳构作用的机理。
